What combines the capabilities of a standard switcher with a distribution amplifier?

A matrix switcher effectively combines the functionalities of a standard switcher and a distribution amplifier, allowing for versatile control over multiple signal sources and destinations. In a typical setup, a matrix switcher can route multiple input signals to multiple outputs, enabling users to select which input is sent to which output at any time.

The distribution amplifier aspect comes into play because matrix switchers can also amplify the signals they distribute. This amplification ensures that the signals maintain their strength and quality over long distances, which is essential in an AV setup where signal integrity is critical.

This dual capability provides significant flexibility in complex AV environments, such as in conference rooms or large installations, where various devices may need to connect to multiple displays or projectors. The other options do not offer this combination of switching and amplification functionalities, making the matrix switcher the most appropriate answer.
